Abstract Magnet–superconductor hybrid (MSH) systems have recently emerged as one of the most significant developments in condensed matter physics. This has generated, last decade, a steadily rising interest understanding their unique properties. They been proposed promising platforms for establishment topological superconductivity, which holds high potential application future quantum information technologies. Their emergent electronic properties stem from exchange interaction between magnetic moments and superconducting condensate. Given atomic-level origin such interaction, it is paramount importance to investigate new magnet–superconductor hybrids at atomic scale. In this regard, scanning tunneling microscopy (STM) spectroscopy are playing crucial role race unveil fundamental MSH systems, with aim discover materials capable hosting topologically non-trivial unconventional phases. particular, combination STM studies tight-binding model calculations represented, so far, successful approach explain MSHs. The scope review offer broad perspective on field MSHs an investigation point-of-view. focus discussing link ground state hosted by system corresponding phase. done both one-dimensional (atomic chains) two-dimensional lattices thin films) proximitized conventional s-wave superconductors.
